  • 功能：
    Interacts with EME1 and EME2 to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5'-end at the branch nick. Typical substrates include 3'-flap structures, replication forks and nicked Holliday junctions. May be required in mitosis for the processing of stalled or collapsed replication forks.
  • 基因功能参考文献：
    1. Replication fork progression in BRCA2-deficient cells requires MUS81. MUS81 nucleolytic activity is required to activate compensatory DNA synthesis during mitosis and to resolve mitotic interlinks, thus facilitating chromosome segregation. PMID: 28714477
    2. Using RNAi or FA-P cells complemented with SLX4 mutants that abrogate interaction with MUS81 or SLX1, we show that SLX4 cooperates with MUS81 to introduce DSBs after replication stress but also counteracts pathological targeting of demised forks by GEN1. PMID: 28290553

Moreover, downregulation of MUS81 increased the sensitivity of epithelial ovarian cancer (EOC)cells to olaparib by inducing S phase arrest and promoting apoptosis through activation of MCM2. MUS81 may be a potential novel therapeutic target for EOC. PMID: 29393493

    24. This study identified a winged helix domain within the N-terminal region of human MUS81 that binds DNA, increases the activity of MUS81-EME1/EME2 complexes and influences the incision position of MUS81-EME2 but not MUS81-EME1 complexes on synthetic forks, 3' flaps and nicked Holliday junctions. PMID: 23982516
    25. Data show that three structure-selective endonucleases, SLX1-SLX4, MUS81-EME1, and GEN1, define two pathways of Holliday junctions (HJs) resolution in HeLa cells. PMID: 24076221
